Funny you mention this - I'm having this exact challenge but with a twist. Last year I realized I was in a total cooking rut so made myself start cooking other people's recipes - from cookbooks, magazines, blogs, websites, you name it I cooked it.

Somehow, I managed to complete over 300 new to me recipes in 2009. Have started afresh in 2010 and while I'm almost at 100, my goal is to do 365 new recipes. There were a lot of winners in last years bunch so it's really hard not to go back to some of the better recipes.

I'll admit, I've been back to the well twice (but not in the last month) - once for a Peruvian Aji Chicken recipe from here on Chow and a second time for this Ribeye rubbed with a fennel rosemary rub (amazing).

It's not easy to not repeat but can be done if you have an open mind and willing palate.
